Sample contract is not deployed. Not enough gas

[StanislavMakarov]

Transfer transaction works OK, but deploy fails. What's wrong? Source code: ContractGasProvider contractGasProvider = new DefaultGasProvider(); try {

        contract = Greeter.deploy(
                web3j, credentials,
                contractGasProvider,
                "Hello!"
        ).send();
        contractAddress  = contract.getContractAddress();
        System.out.printf("Contract Address : " + contract.getContractAddress());
    } catch(Exception e){
        e.printStackTrace();
    }

This might look like a studio and obvious question(s) but...

• Does the account on your credentials object has enough Eth for the GAS_PRICE * GAS_LIMIT set for the Tx?

@JoaquimLey this is not the issue. This error means that the contract deployment has gone over the gas limit.

@StanislavMakarov have you modified the contract constructor method? What network are you connecting to?

@iikirilov Thanks for correcting me 🙏 That's the Tx I was referring to, the actual deployment but I see how confusing might wording might've been :).
